LARYNGEAL PARALYSIS IN THE OLDER DOG. Bryden J. Stanley, BVMS, MVetSc, DACVS. Michigan State University, East Lansing, MI. The larynx sits at the top of the trachea, where it quite effectively protects the lower airway from aspiration of unwelcome materials. It also modulates airflow during increased exertion, coughing, increased intra-abdominal pressure, and vocalization. Airflow is controlled by active abduction or adduction of the paired arytenoid cartilages dorsally and tensing of the vocal cords ventrally ( sliding doors ). Further fortification against aspiration during swallowing is obtained by passive caudal movement of the hinged epiglottis ( trapdoor ). Acquired LARYNGEAL PARALYSIS : What has been known forever . Acquired LARYNGEAL PARALYSIS has been documented in the literature for almost 40 years, presenting as a common condition in OLDER dogs, particularly the Labrador retriever, but also other purebreds (such as German Shepherds, Golden Retrievers, Australian Shepherds, Borzois, Greyhounds, Newfoundlands, Brittany Spaniels) and mixed breeds.
